Queue issues with Ciphering program

Question

Hey guys I have a problem with understanding how to read the file reads in integers that are one the first line...and ends reading integers when the new line of letters come up. This program takes an in.dat file which contains 3 lines (3 4 5 6 4 knowledge is power xyyyxxxyxyx) where the ints are the repeating keys and the letters are encoded with each key then the keys repeat. Can someone help me make a Queue that takes in the keys, assigns to a letter and then the key goes back to the other end of the queue(circular). Also if you can help me with any other parts of my code, that would be nice too. I'm also having trouble adding letters in the alphabet and wrapping aorund (like when the letter is z to go back to a)...the letters are also in a Queue I would imagine.
Thanks in advance. Really I appreciate it all the help I can get.
Here's my code so far:
import java.io.*;
import java.util.*;
public class RepeatingKeyCipher<E>
   public static void main(String[] args) throws IOException {
       RepeatingKeyCipher obj = new RepeatingKeyCipher();
       Queue file = new LinkedList();
       FileReader r = new FileReader("in.dat");
       BufferedReader inFile = new BufferedReader(r);
       PrintWriter outFile = new PrintWriter(new FileWriter("out.dat"));
               while (inFile.ready()) {
                   String s = inFile.readLine();
                file.offer(s);
            inFile.close();
              outFile.close();
          String alpha = "abcdefghijklmnopqrstuvwxyz";
          Queue<String> alphaQueue  = new LinkedList<String>();
          alphaQueue.offer(alpha);
          Queue<Integer> key = new LinkedList<Integer>();
          key.offer(file.);
          for(int i = 0; i < message.length; i++) {
          //     while
     private int front;
     private int rear;
     private int size;
     Queue<E> alpha1 = new LinkedList<E>();
     /*public E encode (int key, String message) {
          StringTokenizer st = new StringTokenizer(message);
          String newWord;
          while(st.hasMoreTokens()) {
               String word = st.nextToken();
               for(int i = 0; i < word.length(); i++) {
                    char letter = word.charAt(i);
                    //char newLetter = alpha.
          return newLetter;
}

By the way I'm not in the same classes as those other kids with cipher programs... weird that they have cipher programs to do too...but mine has to do with repeating keys and queues...and I don't know them
Just had to clarify, thanks
